初始化Anchor BorshCoder实例时抛出IdlError错误（JS）

问题根源 #

你碰到的IdlError: Type not found: undefined，是因为Raydium官方仓库的该IDL存在字段引用缺失问题，部分类型定义未完整关联，导致Anchor的BorshCoder无法正常解析。

修复后的可用IDL #

下面是经过修复、可直接使用的Raydium AMM IDL核心结构（完整使用需补充全量指令，此处展示关键类型与初始化指令）：

使用注意 #

• 若需完整功能，需补充swap、addLiquidity、removeLiquidity等全量指令定义，确保所有类型引用无遗漏。
• 确认你的@coral-xyz/anchor版本在0.29.0及以上，版本不兼容也可能引发解析异常。
